BMW Fuel Drain


Putting Petrol in a Diesel BMW is a regularly occurring mistake to make. And its remedy depends on a variety of factors. In the event that you would like to know what you have to do to sort it out then continue reading.
Let us discuss the most crucial factors to take into consideration whenever making a decision whether to get it drained:

  1. What amount of Petrol have you put in to the BMW, taking into consideration that the fuel tank capacity of your BMW x6 D is in most cases around 85 litres?
    1. Hardly any Petrol, something like 4.25 litres of Petrol in a Diesel x6 D will in most situations not be a major problem. Experience has proven to us that an amount less than 4.25 litres (close to 5% of the fuel tank volume) is frequently capable of being completely diluted by entirely topping up the remainder of the tank with the right fuel.
      It's quite rare to come across a car or truck going through issues due to below 5% incorrect fuel contamination. Please remember it's rare - certainly not impossible to find. You can get a few motor vehicles that will not endure any degree of contamination in the slightest.
    2. Somewhere between 4.25 and 8.5 litres of Petrol in the BMW (from 5 to 10%) is a 50/50 condition. Our expertise has demonstrated that as many drivers get away with it as those who don't. Any time you're deciding on whether to chance it and just fill it up recognise that it is the same as betting it all on black - you will have a 50/50 possibility of it working out.
    3. Anything over 8.5 litres of Petrol in a Diesel x6 D ought to immediately be removed as your likelihood of driving with this quantity of contamination is more than likely below one in 50 - extremely long odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you detected any kind of performance issues as a result of putting the incorrect fuel in the x6 D? If that's the case, get it drained regardless of the volume of Petrol or even the contamination percentage. Continually running a vehicle that is currently beginning to suffer the effects of wrong fuel contamination will only result in increasing amounts of harm affecting your fuel system.
  3. Are you looking for reassurance?
    Then simply just get it drained. Regardless of the contamination percentage, there is inevitably some amount of threat caused by driving a Diesel vehicle on fuel contaminated with Petrol. Likely outcomes of driving a vehicle on the incorrect fuel can include the engine refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are a few of the most frequently seen Petrol in Diesel signs and symptoms, and should you detect any of them cease driving and get it removed as soon as possible.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?


No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?


This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
